COAL STOVE OR FURNACE.

SPECIFICATION forming part of Letters Patent No. 616,651, dated December 27, 1898.

Application filed January 5, 1898. Serial No. 665,633. (No model.) I

To aZZ- whont it may con/007%:

Be it known that I, JAMES Bonn, grocer, of Toronto Junction, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Coal Stoves or Furnaces, of which the following is a specification.

My invention relates to improvements in coal stoves and furnaces; and the object of the invention is to devise a simple attachment whereby when the grate is shaken the cinders and ashes falling therefrom may be simultaneously sifted, so that the cin ders may be separated from the ashes without any dust whatever and without the necessity of employing a separate cinder-sifter outside of the stove or furnace itself; and it consists, essentially,of providing underneath the grate an ash-pan having superimposed upon the suitable supports within the pan a sifter of a suitable mesh, such sifter being provided with an upwardlyextending bracket in the front thereof having an opening directly opposite the socket of the grate in which the shaking-rod is placed, the bracket also having formed at the lower end a supplemental socket by which a movement maybe imparted to the sifter alone, as hereinafter more particularly explained.

Figure 1 is a sectional perspective view of a hot-air furnace provided with my improved attachment. Fig. 2 is a detail of the bracket attached to the sifter.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the grate of the furnace.

B are the rest-bars upon which the grate is supported.

O is a socket attached to or forming part of the central slide portion 0 of the grate.

D is an ash-pan, preferably circular in this case and provided with angular lugs CZ near the top edge thereof, upon which is supported the circular sift-er E, which is provided with a wire-cloth e of any suitable mesh.

F is a bracket attached to or forming part of the front of the sifter E. The bracket is provided with an upper opening f and lower socketf. The upper openingf is designed to be directly opposite the socket C, so that the shaking-bar G (shown in dotted lines) may be inserted through such opening into the socket O. The bar G of course is first inserted through the damper II in the front doorI of the furnace.

It will be noticed by opening the damper II, as shown in the drawings, that not only may the grate be shaken but also the sifter thereby, as the cinders and ashes fall from the grate, sifting them, so that the cinders are retained in the sifter and the ashes fall into the ash-pan D below, thus effecting in the one operation the complete separation of live coals, cinders, and ashes.

Should the ashes not be completely separated from the cinders, the shaking-bar G may be inserted into the lower socket f and the cinder-sifter given an extra shaking. In practice, however,.I find that this is very seldom necessary.

During the process of shaking of course the draft through the furnace will carry up all dust from the shaking, and thereby not render the task a disagreeable one to the attendant of the furnace or stove, as the case may be.

At any time after the shaking is accomplished the cinder-sifter and ash-pan may be removed from the bottom of the furnace through the door I, and the ashes may be of course carried out and the cinders thrown into the coal-bin or furnace,as maybe desired, and this, too, without any dust or dirt.

Although I show my invention as applied to furnaces, it will of course be understood that the invention is equally applicable to self feeding coalstoves, and to cookingstoves, whether square or round, as the sifter may be shaken circularly or longitudinally.

What I claim as my invention is- 1. In a stove or furnace, the combination with the grate and shaking socket and inclosing casing having a door provided with a suitable opening, of an ash-pan located in the casing beneath the grate, a cinder-sifter supported above the same and provided with an extension-bracket having an opening opposite the shaking socket of the grate de signed to receive the shaking-bar as and for the purpose specified.

2. In a stove or furnace, the combination with the grate and shaking socket, and inclosing casing having a door provided with a suitable opening, of an ash-pan located in the casing beneath the grate, a cinder-Sifter supported above the same and provided with an extension-bracket having an opening opposite the shaking socket of the grate designed to receive the shaking-bar and a supplemental socket attached to the bracket substantially opposite the opening in the casing as and for the purpose specified.

3. In a stove or furnace, the combination with the grate-bar and socket and inclosing' casing, of an ash-pan located in the casing beneath the grate, a cinder'sifter supported above the same and provided with an upward extension and means for connecting the shaking-bar to such upward extension and to the shaking socket whereby both Sifter and grate may be shaken together as and for the purpose specified.
